2C (master mode) compatible Clock signal. Note: the pin is

configured as an open drain output. When the I2C interface

is being used, an external pull up resistor is required. A

value of 3K is recommended.

2C (master mode) compatible data I/O. Note: this pin is

bi-directional. When the pin is configured as output, it is an

open drain output. When the I2C interface is being used, an

external pull up resistor is required. A value of 3K is

recommended.
